Refractories 101 | 2013-04-01 | Ceramic Industry

Refractories are materials that resist high temperatures, liquid slags and aggressive atmospheres, and do not change form (e.g., burn or melt) in service. Typically used at temperatures above about 500°C, these materials maintain their critical physical and chemical properties at the temperatures required to make other high-melting-point products.
